Pomacea columellaris is a South American species of freshwater snail in the apple snail family, Ampullariidae . [2]
Pomacea columellaris was originally described as Ampullaria columellaris by Augustus Addison Gould in 1848, based on a holotype shell collected during the United States Exploring Expedition from 1838-1842. [3] They were named for their notable columella, comparable to those of Helix land snails. [4] In 1904, Dall proposed a section or subgenus of Ampullaria (later treated as synonymous with Pomacea ) called Limnopomus , [5] with A. columellaris as the type species. [6] After 1991, Limnopomus was also considered synonymous with Pomacea. [7] [8]
The species has a heavy, oval shell with a sharp spire. [9] Its operculum is corneous and able to retract inside the shell's aperture. [9] [10] They lack an umbilicus [4] and are often yellow in color. [10]
P. columellaris is found in rivers in the highlands of Venezuela, Colombia, Ecuador (Pastaza Province), [11] and Peru. [5]
